Darabont told the Daily Blam that future episodes will focus on the "conflict" between the show's central characters.
"It's fair to say that the first six episodes [that made up season one] were teeing up a lot of conflicts that will be more fully explored in our second season," he explained. "We find a growing conflict with our two main guys, Rick (Andrew Lincoln) and Shane (Jon Bernthal)."
Darabont added that he is excited about "putting all of the characters on a chessboard".
"[We'll be] seeing how wonderfully and effectively we can toss conflict into the game," he said.
It was recently announced that The Mentalist actor Pruitt Taylor Vince will star in the new season of The Walking Dead as farmhand Otis.
The series will return to AMC in the US and FX in the UK in late 2011.
